German submarine U-235 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged.

On 14 April 1945, U-235 was heading to Norway with U-1272 when they encountered a small German convoy accompanied by the torpedo boat T17.

Any celebration on T17 was abruptly stilled when amongst the wreckage appearing were bodies in Kriegsmarine uniform.
